I used to be the same way too, really depressed about everything, like you said I just got tired of everything and the constant difficulties. First time I considered suicide was 14, since then I've had 3 more close calls (28 now).

Make a list of some cool shit you wanna see/ do/ experience before you die, that helped me for a bit. Acid was on my list (other stuff is on the list too), finally got to do it last year, most beautiful experience of my life.

Back to the depression though, after the last close call I ended up on seraquil, which made me feel 'normal.' There's a big trade off though, I couldn't function at all before 10 am (I'd fall asleep after making breakfast) and my thinking was really slow and groggy. After a year or so I stopped taking, and I'm doing pretty good now but it's because of the way I choose to define life.

If you/we define success and happiness by NT standards we will always come up short, because we're not NTs. Long story short if you use a knife as hammer don't be surprised if you end up having a bad day.

Besides, Why is spending every week in a crowded club drinking normal fun, or a normal social life? Why should I care about a deflated football? Because that's what our parents and society is normal? If we never changed and only went by the standards of our senior generation we would still have Lynching Parties in the U.S. - it's still close, but the point is historically deviation from the norm is what evolution (and ethical growth/development) are about.

Peyote's legal in Az, also a worthwhile experience, helped me process a lot of childhood substance abuse issues that arose from trying to make myself fit within societies standards of normal.
